Taxonomy is the science of classification, categorization, and naming of organisms based on their characteristics.

• Taxonomy is a branch of biology that deals with the identification, classification, and naming of organisms.

• It involves organizing organisms into hierarchical groups based on their similarities and differences.

• Taxonomy helps in understanding the relationships between different species and their evolutionary history.

• The classification system in taxonomy includes va...read more

pH formula is a measure of the acidity or alkalinity of a solution.

• pH formula is defined as the negative logarithm (base 10) of the concentration of hydrogen ions in a solution.

• The formula is pH = -log[H+], where [H+] represents the concentration of hydrogen ions.

• pH values range from 0 to 14, with 7 being neutral, values below 7 indicating acidity, and values above 7 indicating alkalinity.

• For example, a solution with a pH of 3 is acidic, while a solution with a pH of 10 is al...read more
